During a preventative maintenance visit in Mechanicsburg, Metro HVAC technician Steve found rust on the evaporator coil. Rust like this can wear through the metal and cause a refrigerant leak. A leaking coil often means a costly replacement and a system that stops cooling.
Steve applied a zinc coating encapsulation to the coil. The coating seals the exposed metal and helps protect it from further corrosion. The work was covered under the homeowner’s Metro HVAC maintenance plan, and the homeowner agreed to let us share the visit.
If an air conditioner is no longer cooling or develops an active fault, see our Mechanicsburg AC diagnostics and repair service. Preventive maintenance and a repair diagnosis are different visits.
Why this matters
- Rust usually starts small and hidden, often in the air handler or basement.
- Catching it early is far cheaper than replacing a coil.
- Regular maintenance is how problems like this get found.
